WitrynaThere is a balance between hardness and toughness in any steel; the harder the steel, the less tough or impact-resistant it is, and the more impact-resistant it is, the less hard it is. Tempering. The term tempering refers to a heat treatment which is used to increase the toughness of iron-based alloys.
